NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Change your PHP to run git via sudo

<?php `sudo git pull [email protected]:my-user/myrepo.git`; ?>

Then change your suoders to allow git to be run by the apache user:

nano /etc/sudoers

	# 1. Put this file under ~/.phpdebug
	# $ curl https://gist.githubusercontent.com/torinaki/9059015/raw/.phpdebug > ~/.phpdebug
	# 2. Put following lines into ~/.bashrc:
	# # Get the aliases and functions
	# if [ -f ~/.phpdebug ]; then
	# . ~/.phpdebug
	# fi
	# 3. (optional) Script will try to autodetect your machine IP where runs IDE or use 127.0.0.1 otherwise.
	# If automatic detection doesn't work for you, set ip directly via IDE_IP enviroment variable:
